soc/mediatek/mt8196: Fix timer reset in BL31

1. Set systimer compensation to version 2.0.
2. After reboot, the system does not need to serve pending IRQ from
systimer. Therefore, clear systimer IRQ pending bits in init_timer().
For that to work, the systimer compensation version 2.0 needs to be
enabled.

TEST=Build pass and timestamp is not reset in ATF and payload
BUG=b:343881008
